ghc/rts Signals.c
Log:
Don't install a SIGFPE handler: this causes us to go into an infinite
loop on a divide by zero on some systems (BSD, but not Linux it
seems). I don't think we really ought to be ignoring SIGFPE: for
floating point exceptions, the system usually has a way to request
that operations generate exceptional values rather than signals (this
is the required IEEE behaviour), and for integral division we should
really check beforehand for division by zero (we don't yet).
